3 Brief: Series YTP diaphragm pressure gauge (chemical seals) is composed of a conventional pressure measuring instrument, a connector and a diaphragm seal. This combination enables a general purpose pressure gauge to measure media of strong corrosion, high temperature, high viscosity, containing suspended matter or crystallizing. Diaphragm gauges are universally used in petrochemical, alkali, chemical fiber, pharmaceutical, metallurgical, and food industries. 2

4 Configuration Principle This illustration shows the operating principle of the diaphragm pressure gauge. The diaphragm is deflected by the pressure of medium P, and an equivalent pressure P is generated. With transmitting through working fluid, the pressure P deflect the elastic element of a pressure measuring instrument which thereafter shows the pressure value. 3

5 Level Difference of diaphragm pressure gauge seals liquid When a diaphragm pressure gauge is mounted with pressure gauge and diaphragm seal at different positions, the effect of level difference should be taken into consideration (especially for a diaphragm gauge with capillary). As the illustration shows, with a S.G. of the working fluid at approx. 1, and a level difference of 1m, the pressure difference is approx. 0.01MPa/cm2. 4

6 The temperature influence of a diaphragm pressure gauge The temperature influence of a diaphragm pressure gauge is relative to expansion coefficient of the seals working fluid, rigidity of the diaphragm, and temperature of pressed part. When working temperature deviates from 20 ± 5, the indication varies within 0.1%/ for rigid system, and within L%/ (L-length of capillary in m.) for flexible system(remote mounting). Diaphragm pressure gauges are filled with suitable working fluid according to different operating conditions. 5
